> Occasional Asterisk core dump during caller id read on analog channel. Further investigation and core dump analysis shows that a negative return value from the read() in my_get_callerid slips through as a negative length argument to callerid_feed() if the errno returned by DAHDI is ELAST. This would likely cause the crash.
